実験手順

In a 1 l. r.b. flask 100 g. (0.6 mole) of 3,4-dimethoxybenzaldehyde, 40 g. (0.52 mole) of ammonium acetate, 50 ml. (0.93 mole) of nitromethane, and 400 ml. of glacial acetic acid were combined and refluxed for 2 hours. The solution was then cooled to room temperature overnight. Yellow crystals were then collected via suction filtration and washed with hexane and ether. 73 g. of desired product were collected with m.p. 133°-134° C.
